Disperse Yellow 3 Usage And Synthesis

Description

Disperse yellow 3 is an azoic dye responsible for occupational contact dermatitis in workers in the textile industry. It can be found in some semipermanent hair dyes.

Uses

Disperse Yellow 3 is an azo disperse dye which is water insoluble. Disperse Yellow 3 can be used to dye polyester and acetate fibers. Dyes and metabolites, Environmental Testing.

Uses

Disperse yellow 3 is used in dyeing textiles, sheepskins and furs; in coloring polymethyl methacrylate and nylon; in the surface dyeing of cellulose acetate; stocking dye.

Preparation

N-(4-aminophenyl)acetamide diazo, and to a p-Cresol?coupling

Definition

ChEBI: An azo dye with a structure consisting of acetanilide substituted on the 4-position of the phenyl group with a 6-hydroxy-m-tolylazo group.

General Description

Brownish-yellow powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water.

Reactivity Profile

Disperse Yellow 3 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Disperse Yellow 3 is incompatible with strong oxidizing agents and strong acids .

Fire Hazard

Flash point data for Disperse Yellow 3 are not available; however, Disperse Yellow 3 is probably combustible.

Contact allergens

This azoic dye is responsible for textile dermatitis from stockings and occupational contact dermatitis in workers in the textile industry. It can be found in some semipermanent hair dyes.

Safety Profile

Suspected carcinogen with experimental tumorigenic and carcinogenic data. Low toxicity by intraperitoneal route. An allergen. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx,.

Properties and Applications
